[Firebird-devel] UPPER does not work with national characters

[Balassa M. <fu...@ma...>]

Try this on a database with character set WIN1250:

SELECT 1 FROM rdb$database WHERE UPPER('abc') = UPPER('AbC')

The above query returns 1 as expected. Now, try it with strings containing
non-us characters (á, é, etc). The result is null.
